Application filed $epten1'ber 19, 1899. Serial No. 731,612. (No model.)

Be it known that I, AL'FRED E. FEROE, a citizen of the United States, residing at Tivoli,- in the county of Dutchess .and State of New York, have invented new and useful Improvements in Ale or Beer Filters,of which the following is a specification. y

My invention relates to an improved ale and beer filter for brewery use.

The object of my improvementis to provide a device of a very large capacity, simple in constructiomstrong, durable, and efficient in operation, and of as'few parts as'is consistent with perfect work.-

To attain these ends the invention comprises a series of filter-sections which when put together form a series of compartments. Each compartment has inlet and'outlet pas sages and means for filtration and is a'complete filter in itself.

The invention further consists in the construction, combination, and arrangement of the several parts of the device, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation, partly in section, of my improved ale and beer filter. Fig. 2is an end elevation of the same. Fig. 3 is atop plan View of the filter. Fig. 4 is a detail view showing the inlet and outlet ports of one of the filten's'ections. Fig. 5 isa bottom plan View of one of the filter-sections. Fig. 6 is a trans verse section on the line y y of Fig. 5. Fig. 7 is an enlarged bottom plan view of the foraminous filter-plate or diaphragm. Fig. 8 is a detail section on the line 00 0a of Fig. 7. Fig. 9 is a similar view on the line y y of Fig. 75'

In the drawings the same reference characters indicate the same parts of the. invention. 1 denotes a carriage or truck mounted on suitable carryingwheels for "conveniently transporting the filter from place to place. This carriage is provided with vertical parallel brackets 2 2, which'support the bearingboxes 3 3, in which are journaled the trunnions at 4: of the rectangular yoke or frame 5, in which the filter proper is 'removahly secured.

6 denotes the bottom filter-section, which rests upon the yoke, and 7 7 denote a series of superimposed and counterpart filter-sections, of which there maybe an indefinite number to correspond to the capacity of the filter, the uppermost one being provided with .a cover-plate 8 and all formed with guidelugs 9 9 to straddle the vertical armsof the yoke. The cover-plate has orificed ears 1O 10,"

which are alined with corresponding ears 12 12 on the bottom section ,6 to receive the clamping-bolts 13 13, which, in connection with the hand-screws 14 14 in the bridge of the yoke,- serve to clamp the contiguous edges of the bottomsection, the cover, andtheintermediate filter-sections together, so as to form air-tight joints between them'andatthe same time permit of their convenient dismemberment when necessary to cleanse and repack the filter.

As hereinbetore stated, the intermediate "sections are counterpart, and consequently the description of one will answer for all.

Each section consists of an annular pan or vessel formed with an imperforate bottom 15 and an annular encompassing flange 16, the

upper edge of which is formed with a continuous groove 17 to receive the gasket or packing 18, and its lower edge is formed with an annular shoulder 19, which forms a joint with the gasket 18 of the contiguous section be neath. The inner wall of the section is formed with a continuously-grooved annular shoulder 20 to receive the gasket'21, on which the foraminous filter-plate 22- rests, the bottom face of which is provided with a series of mp tilated ribs 23, (these ribs are so placed as not to close any of the perforations,) which rest on the upper face of the imperforate bottom 15 of the section to support said plate in position when the filter is packed, which is accomplished by filling the space above said foraminous plate with shredded asbestos, filter mass, or a like material or mixtures of the same, and then placing on top of said material a disk of felt, cloth, or some similar fab ric 25, then pressing them down tightly to a level slightly below the top of the encompassing flange 16. The perforations 23 in-the foraminous plate are funnel-shaped to afford a large drainage area under the 'filteringm'edia, and none of them are closed by the supp0rting-ribs.

It will be noted that the bottom faces of with a circular, border-flange 24, having an aperture at one point for the ale to pass through it. Said flange 24 rests on the cloth,

filter mass, 850., above the corresponding circular imperforate rim 22 of the filter-plate.

(Shown in Fig. 7.)

Each filtering-section is formed with a radial duplex coupling 26 28, as shown'in Fig.

4, the member-26 being formed with a vertical passage'29, from which an inlet-port 3O communicates with the interior of the filtersection above the fabric 25, and the member 28 is'also formed with'a vertical passage-way 31 and a lateral opening 32, which communicates with the outlet-port 33 by means of the pipe :34, the'port opening into the filter-see,

tion below the foraminous plate. The pipe 34 is provided with a plug-cock 35 and with anopen work cage 36, in which is inserted a short section of glass tubing 37, so that the filtered ale or beer may be visually inspected as it leaves each filter-section, and thus it may be ascertained if each compartment is performing its work in a proper manner.

When the filter is assembled, as shown in Fig. 1, suitable packing'beingof course placed between the contiguous plane faces of the couplings, the entire series of alined members 26 constitute a continuous inlet-pipe 26' and the corresponding series of alined members 28 likewise form a continuous outletpipe'28. The lower end of the inlet-pipe 26' I is connected with a supply-pipe 38, which communicates with the ale or beer tank, (not shown,,) and its upper end with a vent-pipe 38', extending to the top of said tank,wherebythe disengaged gas is carried out of the filter and returned to the beer-tank, thereby avoiding the necessity for a gas-trap or other similar device. The lower end of the outletpipe 28 is also provided with a dischargepipe 39, which communicates with a racker or a racking-tank, (not shown,) and its upper end with avent pipe'39, which also communicates with said racker or racking-tank, thereby avoiding the use of a gas-trap and the attention it'requires. The upper ends of both the vertical inlet and outlet pipes are provi'ded with pressure-gages, as shown, and the inlet-pipe is in addition provided with a thermometer, the object of the pressure and heat gages being obvious.

In operation the ale or beer from-the tank I passes through the supply-pipe 38 and through the vertical inlet-pipe 26 and ports 30 into the filter -sections, thence downwardly through the cloth fabric, asbestos, or other filtering material and foraminous plate into the bottom of each filter-section, from which the filtered ale escapes through the outlet-ports 33 and pipes 34 into the vertical outletepipe 28', and thence through the discharge-pipe 39 to the racker or racking-tank, the air and disengaged gases escaping through the ventpipes 38' and 39'. I

As above described, the filtering process is conducted downwardly; but it may just as easily be conducted upwardly by reversing the filter on its trunnions, or horizontally, if

'desired,'b'y adjusting the filter proper to a corresponding position. In case it is desired -to filter upwardly the positionof the beerpipes and the vent-pipes will have. to be reversed'and the location of the pressuregages and the thermometer correspondingly changed. g

I A filter thus constructed possesses many advantages in point of utility. Its capacity is practically unlimited. It may be increased or diminished by the addition of or removal.

of filter-sections, and the result of the work of each individual compartment is always open to inspection. reversible, and it can be thoroughly and rap- ,idly cleaned out by passing steam and hot water in the reverse direction through the filtering-compartments, and it can be'conveniently taken apart and easily and quickly repacked and made ready'for use, or any single compartment doing defective work may be closed without disturbing the others.

, It will of course be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
